People who think "anime" woman look like children are ignorant of anime. There's usually a difference between how adults and children are drawn, as the adults often possess noticeable facial traits that the children do not. It can be subtle, but for the connoisseur it's usually pretty unmistakable too. This is why there's a clear distinction between loli art and other types of hentai. Obviously there are exceptions to everything, but then it's those same people who might generalize all anime to look a certain way that would be ignorant of the vast array of stylistic differences within anime.
Also, the DOA girls do not look like children. It annoys me when people say that, as they clearly don't understand that many of these characters are based off of youthful Asians with anime characteristics. To them that possibly translates to "child", but anyone who's had experience drawing children, anime, and Asian people can tell you there's a difference. If you put Kasumi's head on a child's body you'd probably notice something was off. In reality, it's no different than being attracted to a Ariel or Tiana. That's only some of the cast, too. Characters like Tina, who are obviously supposed to look American, have even more adult characteristics. What bothers me most is that people are so quick to judge others as pedophiles for simply finding a youthful facial type attractive. Hey, guys, there a REAL adult woman in this world who happen to look young for their age. That doesn't mean we should start slinging accusations of pedophilia (especially since ephebophilia would be a more accurate, if still potentially unwarranted, descriptor).
